It acts as a companion to the EN 1992 standards, helping engineers interpret the often-dense code text into actionable design procedures. Key Areas Covered in Volume 2
Additionally, some examples assume proprietary software for analysis (e.g., for bridge moving loads). This is acceptable, but the book should have included a manual influence line check.

(officially BS EN 1992-2 ) specifically addresses the design of concrete bridges . While Volume 1 focuses on general rules and building design, Volume 2 expands these principles to handle the complex loading and durability requirements unique to bridge engineering.

= Max allowable stress in reinforcement immediately after cracking. For a crack limit with bars, assume based on Eurocode lookup tables.
MEd = 1.35 x (2 x 4^2 / 8) + 1.5 x (1.5 x 4^2 / 8) = 18.9 kNm
The beam requires additional shear reinforcement. It acts as a companion to the EN

is a technical publication, often produced by professional bodies or industry experts, that offers step-by-step design calculations for advanced or specialized concrete structures. While Volume 1 typically covers basic elements like beams, slabs, and columns, Volume 2 dives deeper into more complex, specialized problems.
